State of matter

Question 1

Solid

Answer 1

Can be melted

Definite shape

Made up of particles

Strong attractions

Made up of particles in fixed position

Can be condensed

Strong connection between particles

A solid is where the particles have a very strong bond and are forced together. Solids are different to liquids are gasses because they don’t have a as strong bond as solids do. But one thing they have in common is all the particles vibrate

Question 2

Gases

Answer 2

Contain partials free to move

Made up of particles

Easy to compress

Expand to fill a container

Can be poured

Can be poured

Weaker connection between particles

A gas is where the particles are freely to move and have no connection with each other. This is different to a liquid and a solid because a liquid and a solid always as some sort of connection and are always touching. The strength of the forces between the gas particles are weaker than solids and liquids.

Question 3

Liquid

Answer 3

Made up of particles

Can be poured

Weak connection between particles

A liquid is where the particles are like friends but not best friends so this means they have a bond but not a strong bond. Liquid is different to solids and gases because a liquid is the only state of matter that can be poured. A liquid vibrates more than a solid.

Question 11

What are the mobile phase and stationary phase?

Answer 11

The water is a mobile phase

The paper is the stationary phase

Question 12

What is the key idea of Chrome a Toh Graffi?

Answer 12

More soluble- longer distance

Less soluble- Shorter distance

Question 13

Solute

Answer 13

The substance dissolved (element, compound) - Gets dissolved

Question 14

Solvent

Answer 14

Dissolved the solute – dissolves it

Question 15

Solution

Answer 15

The solute and solvent together

Question 16

Saturated

Answer 16

When no more solute can be dissolved in a solvent

Question 17

What does solvation mean?

Answer 17

The interaction of solvent and a solute

Question 18

Calculate Rf

Answer 18

Divide the distance travelled by the component by the distance travelled by the solvent.

Question 19

What is solubility?

Answer 19

How easily something dissolves

Question 20

What do you see when the solute has been put into the solvent?

Answer 20

I see the solute going into the solvent and the solvent is breaking the solute away and finally it turns into a solution

Question 21

What are the separation techniques?

Answer 21

Distillation, crystallisation, fractional distillation, evaporation, filtration, Distillation, Magnetic Separation, Sieving and Chromatography.
